[AS3]as3.0运用JPGEncoder来生成与保存图片源代码实例JSP版

晚上正好能静下心来，把工作中用到Flash位图数据保存整理一下，写了下面的应用实例。

package project.test {   
       
    import flash.display.*;    
    import flash.net.*;   
    import flash.events.*;   
    import flash.utils.ByteArray;   
       
    import fl.controls.Button;   
       
    import com.klstudio.images.JPGEncoder;   
       
    public class Test12 extends Sprite{   
        private var _base:Shape;   
        private var _rnd_button:Button;   
        private var _submit_button:Button;   
           
        private static const UPLOAD_PAGE:String="http://localhost:8080/upload.jsp";    
           
        public function Test12(){              
            _base = new Shape();   
            _base_base.x = _base.y = 5;   
            addChild(_base);               
            drawLine();        
               
            _rnd_button = new Button();   
            _rnd_button.label = "CuPlayer.com提示随机画图";   
            _rnd_button.setSize(90,22);   
            _rnd_button.move(5,205);   
            _rnd_button.addEventListener(MouseEvent.CLICK,clickHandler);   
            addChild(_rnd_button);

            _submit_button.move(105,205);   
            _submit_button.addEventListener(MouseEvent.CLICK,clickHandler);   
            addChild(_submit_button);   
        }   
           
        public function drawRndRect():void{   
            _base.graphics.beginFill(getRndColor());   
            var gWidth:uint = getRndInt();   
            var gHeight:uint = getRndInt();

            return uint(Math.random()*(max-min))+min;   
        }   
           
        public function getRndColor():uint{   
            var r:uint = getRndInt(10,220);   
            var g:uint = getRndInt(10,220);   
            var b:uint = getRndInt(10,220);   
            var c:uint = (r << 16) + (g << 8) + b;   
            return c;   
        }   
           
        public function drawLine():void{               
            _base.graphics.beginFill(0x666666);   
            _base.graphics.drawRect(0,0,190,190);   
            _base.graphics.beginFill(0xFFFFFF);   
            _base.graphics.drawRect(1,1,188,188);   
            _base.graphics.endFill();   
        }   
           
        public function getBitmapData():BitmapData{   
            var bmd:BitmapData = new BitmapData(_base.width,_base.height);   
            bmd.draw(_base);   
            return bmd;   
        }   
           
        public function submit():void{   
            _rnd_button.enabled = false;   
            _submit_button.enabled = false;   
            var encoder:JPGEncoder = new JPGEncoder(80);   
            var bytes:ByteArray = encoder.encode(getBitmapData());   
            var request:URLRequest = new URLRequest(UPLOAD_PAGE);   
            //data值就为图片编码数据ByteArray;   
            request.data = bytes;   
            request.method = URLRequestMethod.POST;   
            //CuPlayer.com提示这个是关键,内容类型必须是下面文件流形式;   
            request.contentType = "application/octet-stream";   
               
            var loader:URLLoader = new URLLoader();            
            loader.addEventListener(Event.COMPLETE, completeHandler);   
            loader.addEventListener(IOErrorEvent.IO_ERROR,errorHandler);   
            loader.load(request);   
        }   
           
        private function completeHandler(event:Event):void{   
            trace("CuPlayer.com提示图片上传成功");   
            _rnd_button.enabled = true;   
            _submit_button.enabled = true;   
        }

            _rnd_button.enabled = true;   
            _submit_button.enabled = true;   
        }   
           
        private function clickHandler(event:MouseEvent):void{   
            switch(event.target){   
                case _rnd_button:   
                    _base.graphics.clear();   
                    drawLine();   
                    drawRndRect();   
                    drawRndRect();   
                    drawRndRect();   
                    drawRndRect();   
                    break;   
                case _submit_button:   
                    submit();   
                    break;   
            }   
        }   
    }      
}   

服务端代码(upload.jsp)：我使用是Java服务端，当然PHP,ASP.NET也可以了，我在这里就不一一举例了，有兴趣的朋友自己研究了！

%@ page contentType="text/html; charset=utf-8" language="java"%>   
<%@ page import="java.util.*"%>   
<%@ page import="java.io.*"%>   
<%   
int v;   
String filePath = request.getRealPath(System.currentTimeMillis()+".jpg");   
BufferedInputStream inputStream = new BufferedInputStream(request.getInputStream());   
FileOutputStream outputStream = new FileOutputStream(new File(filePath));   
byte [] bytes = new byte[1024];   
while((v=inputStream.read(bytes))>0){   
    outputStream.write(bytes,0,v);   
}   
outputStream.close();   
inputStream.close();   
%>
